Further, the adhesive layer (8) having a foaming agent is an adhesive layer containing a foaming agent, and has properties of raw or foaming properties. That is, the adhesive layer () containing a foaming agent is a heat-peelable adhesive layer (or a heat-expandable adhesive layer). The adhesive layer (8) containing a foaming agent contains at least an adhesive and a foaming agent. Therefore, when the adhesive layer (Β) of the foaming agent is adhered to the workpiece (adhered body) and solidified, the processed product is firmly fixed to the foamed product. On the adhesive layer of the agent, it can be processed smoothly. After processing, the adhesive layer (7) containing the foaming agent is heated to foam and/or thermally expand the foaming agent. The adhesive layer (8) of the foaming agent is expanded, and by the expansion, the adhesive layer (Β) containing the foaming agent and the post-processing area (contact area) of the processed product (adhered body) are reduced, and the foaming is contained. The adhesive force of the adhesive layer of the agent is reduced, and the processed article can be easily peeled off without any damage on the heat-peelable double-sided adhesive tape or the adhesive sheet. The foaming agent is not particularly limited, and a heat-expandable microsphere can be suitably used. The foaming agents may be used singly or in combination of two or more. The heat-expandable microspheres can be suitably selected from known heat-expandable microspheres. As the heat-expandable microspheres, a microencapsulated foaming agent can be suitably used. The heat-expandable microspheres are, for example, those which have an elastic inner shell, I27476.doc -30-200844206, and a small ball which can be easily vaporized and expanded by heating. . In many cases, the above-mentioned shell is formed of a thermally fusible substance or an object f which can be destroyed by thermal expansion. Examples of the material for forming the above-mentioned shell include a vinylidene chloride-acrylic copolymer, a polyethylene glycol, a κ ethylene butyraldehyde, a methyl methacrylate, a polyacrylonitrile, and a polyvinylidene oxide XK stone. Wind and so on. The heat-expandable microspheres can be produced by a conventional method such as a coagulation method or an interfacial polymerization method. Further, among the heat-expandable microspheres, for example, a commercial item such as "Matsumoto Micr〇sphere" [made of Matsumoto Oil & Fats Co., Ltd.] is also available. # In the present invention, as the foaming agent, a foaming agent other than the heat-expandable microspheres may be used. As such a foaming agent, various foaming agents such as various inorganic foaming agents or organic foaming agents can be suitably used and used. Typical examples of the inorganic foaming agent include ammonium carbonate, ammonium hydrogencarbonate, sodium hydrogencarbonate, ammonium nitrite, sodium borohydride, various azides, and the like. & As a representative example of the organic foaming agent, for example, water, trimethylmonofluoromethane, dioxane, early fluoromethane, or the like, a gas-fired hydrocarbon system, a compound; 35 nitrogen diisobutyronitrile, azo = An azo compound such as formamide or arsenazodicarboxylate; p-toluenesulfonyl fluorene-p-phenylindole-3,3'-disulfonyl hydrazine, 4,4,-oxybis(benzene sulfonate) Anthracene compounds such as fluorenyl hydrazide, propylene bis(sulfonyl hydrazine); amines such as hydrazine, hydrazinocarbazide, 4,4,-oxybis(phenylsulfonylhydrazide) Urea compound '"5-morphinyl], 2,3,4-thiatriazide and other three-sigma sitting compounds; n, n, dinitroso-amyltetramine, N, N, _ diterpene An N-nitroso compound such as a base-N,N,-dinitroso-p-xylyleneamine or the like. The straw is heat-treated, so that the adhesive layer (B) containing the foaming agent can be effectively and stably lowered by the force of 127476.doc 200844206, so that the volume expansion ratio is preferably 5 times or more, and more preferably 7 More than double, particularly preferably a foaming agent which is more than 1 time but not moderately ruptured. The blending amount of the foaming agent (heat-expandable microspheres, etc.) can be appropriately set according to the expansion ratio of the adhesive layer (Β) containing the foaming agent or the reduction of the adhesive force, etc., usually with respect to the formation of the adhesive containing the foaming agent. The amount of the adhesive base polymer (10) of the agent layer (8) is, for example, (10) parts by weight, preferably

C Ο 10 to 130 parts by weight, and more preferably 25 to 100 parts by weight. As an adhesive for the adhesive layer of the foaming agent, it is particularly limited to an adhesive which can be used as an adhesive for the adhesive layer (8) which is not exemplified as the foaming agent (for example: propylene) Acid-based adhesive, rubber-knee-adhesive agent, Ethyl-based Hyun-based adhesive, polyglycolic adhesive, polyglycolic adhesive, polyamido-based adhesive, urethane Adhesives, fluorine-based adhesives, styrene-diene post-copolymer adhesives, improved latent properties, adhesives, radiation-curing adhesives, and the like are known and used, and are suitable for use. Adhesive shots are used alone or in combination 2 = upper use. As the adhesive, it is preferred that when the agent layer (8) containing the foaming agent is heated to expand, the foaming agent (heat-expandable U-ball or the like) is foamed and/or expanded as much as possible. As the adhesive, an acrylic adhesive or a rubber adhesive can be suitably used. It is particularly preferable to use an acrylic adhesive. Specific examples of the acrylic acid-based adhesive or the 糸-adhesive agent are exemplified as the specific examples of the above-mentioned adhesive layer (Α) containing no foaming agent.

Further, a stopper, such as a sputum, as a parent or a tackifier, is specifically exemplified. The material (4) (9) of the adhesive layer (4) having a foaming agent can be, for example, a conventional agent, a foaming agent (heat-expandable microsphere, etc.), and a solvent or other additive to be added. Specifically, for example, a layer formed in a sheet shape may be formed. Coating layer (8): a mixture containing a foaming agent, a foaming agent (heat-expandable microspheres, etc.), or an rubber agent or other additive, which is formed by a method such as a squeezing method, is applied to an elastic layer of a substrate machine. 'Method of drying or hardening as needed; the second is to transfer (move) to a suitable septum (the method of peeling off the adhesive layer of the foaming agent, forming the cloth-containing elastic layer on the cloth) The base material or the rubber material may be a single sound, a plurality of shores, and an adhesive layer w 々 an early layer or a plurality of layers of a foaming agent. s Adhesive layer with a foaming agent B ^ ^ ^ ^ ^ ^ Sex and other suitable choice, heart 45 ~ 22 according to the reduction of the power of the left six gays 勹 5 300 called ^ better 20 ~ 150 μιη workers right.

The heat-expanding of the adhesive layer (8) containing the foaming agent can be controlled with the same degree (high precision) to make the adhesive layer containing the foaming agent (B) Preferentially and uniformly expands in the thickness direction. That is, the rubbery organic elastic layer functions as follows. When the heat-peelable double-sided adhesive tape or adhesive sheet is adhered to the adherend, the surface is provided with the surface shape of the adherend. The larger the area of the anastomosis is to use the self-heating release type double-sided adhesive tape or adhesive sheet to peel off the adherend, and heat the foaming agent-containing adhesive layer (B) to foam and/or inflate. , reducing the foaming and/or expansion constraint of the heat-peelable double-sided adhesive tape or the direction of the adhesive sheet, so that the adhesive layer (b) containing the foaming agent has a three-dimensional structure, 127476.doc -34- 200844206, Thereby promoting the formation of an undulating structure.

Further, if the thickness of the rubber-like organic elastic layer is too small, the three-dimensional structural change cannot be formed after heating and foaming, and the peelable rubber-like organic elastic layer may be a single layer or a rubbery organic layer of two or more layers. The elastic layer may also be formed of an adhesive material mainly composed of a natural rubber knee or a synthetic rubber or a rubber-elastic synthetic resin, and may be formed by using a foamed film mainly composed of related components.
